Description
The TS393 is a micropower CMOS dual voltage
comparator with extremely low consumption of
9µA typ / comparator (20 times less than bipolar
LM339). Similar performances are offered by the
quad micropower comparator TS3702 with a
push-pull CMOS output.
Thus response times remain similar to the LM393.

1. All voltage values, except differential voltage, are with respect to network ground terminal.
2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.
3. Excursions of input voltages may exceed the power supply level. As long as the common mode voltage
[V
icm
=(V
in+
+ V
in-
)/2] remains within the specified range, the comparator will provide a stable output state.
However, the maximum current through the ESD diodes (IF) of the input stage must strictly be observed.
4. Guaranteed by design.

6. Human body model, 100pF discharged through a 1.5kΩ resistor into pin of device.
7. Machine model ESD, a 200pF cap is charged to the specified voltage, then discharged directly into the IC with
no external series resistor (internal resistor < 5Ω), into pin to pin of device.
